Title: Machine for discharging granular or powdery material, e.g. fertilizer
Inventor: HIGGEN REINHARD
IPC: B65G23/12
Filed: 1983-01-27
Abstract: The machine has a chassis and an elongate storage container (1) provided at one end with a discharge opening (2) and in its lower region with a conveying device for conveying the material disposed in the storage container to the discharge opening. The conveying device is formed as a conveyor belt (3) which is guided round a drive pulley (4) and a guide pulley and which, when viewed in the direction of movement of the conveyor belt, is also guided over a snub pulley (6) directly behind the drive pulley in order to increase the angle of wrap of the conveyor belt at the drive pulley. In order to provide, in the smallest possible space, a drive for the conveyor belt which is resistant to slipping, even under the most difficult conditions, the snub pulley is driven as a function of the drive pulley and the peripheral speed of the snub pulley is slightly higher than the peripheral speed of the drive pulley. <IMAGE>

Patent GB-2136095-A (GB)
Title: Gas pressure regulator
Inventor: THOMPSON BARRY
IPC: F16K47/00
Filed: 1983-03-03
Abstract: A gas pressure regulator for supplying gas to a gas distribution network has a control valve 3 operated by a flexible diaphragm 5 urged in one direction to open the control valve by a spring 7. A feedback pipe 8 supplies gas from the downstream side of the control valve to the opposite side of diaphragm to act against the spring. An acoustic filter arrangement 12 comprising two Helmholtz resonators 14 and 15 is incorporated in the feedback pipe to attenuate feedback of acoustic pressure waves which might otherwise prevent the maintenance of a predetermined steady downstream gas pressure. Each resonator comprises a coiled tube (26) surrounding and feeding into an annular cavity (27). <IMAGE>

Title: Locks
Inventor: CAHILL DERMOT JOSEPH
IPC: E05B47/00
Filed: 1983-09-02
Abstract: A lock includes a solenoid- operated striker unit 4 for capturing pin-bolts 9 of the shot bolt assembly 3 of a key-operable locking mechanism 1 of a hinged door 2. The pin-bolts 9 are captured within a keep channel- member 13 that slides up and down within a fixed channel-member 10 between an upper, release position and a lower, locking position. The member 10 is set perpendicularly to the general plane of swing of the door 2. A catch 19 latches the member 13 in the release position until released, allowing the member 13 to move to its locking position under spring action, in response to entry of the uppermost pin- bolt 9 into the striker unit 4. Alternatively (Figure 9), a solenoid-lifted cylindrical keep-member 41 rotates about its longitudinal axis in admitting pin-bolts 44 to, and releasing them from, axially- directed slots 46 that capture the pin- bolts 44 when the member 41 moves downwardly under resilient bias. <IMAGE>

Title: Photographic colour print processing equipment
Inventor: WILLIAMSON DAVID THEODORE NELS
IPC: G03D13/04
Filed: 1984-03-05
Abstract: An automatic photographic colour print processor designed for amateur use to eliminate the wastage of chemicals inherent with most existing designs, but giving all the advantages of unattended processing and the ability to change the process at will, even between prints. The principle is to release pre-measured quantities of processing solutions in a pre-arranged sequence from containers into a modified conventional processing unit, draining each solution from the processing unit, and optionally segregating it for re-use, before the next solution is dispensed, the whole operation being under the control of a timer/controller which enables each part of the process sequence to be determined and time in advance. In one form the containers 1 are tipped over in sequence by means of cams 7 driven through a common shaft 5 by a solenoid 6 so as to discharge their contents into a common outlet 3. <IMAGE>

Title: Brake pressure control system
Inventor: TAKATA KOJI
IPC: B60T8/62
Filed: 1984-05-03
Abstract: A brake pressure control system for vehicles which employs a data process for antilocking control, booster control and distribution of brake force. The data processor 22 receives signals from detecting means 28 detecting the speed of rotation of the vehicle wheels 1,3 in order to anticipate locking of the wheels and give an antilock control signal. Signals from the data processor 22 are also fed to brake pressure control means 7, 8 in order to achieve a desirable distribution of braking force, as computed by the data processor, to the front brakes 2 and rear brakes 4 even if the locking of the wheels is not detected or foreseen. The sum of and difference between front and rear brake pressure is sensed and controlled to provide both a desired total braking force and a desired front to rear braking ratio. <IMAGE>

Title: Continuous separation system
Inventor: DUCASSE JOSEPH CHRISTOPHE VICT
IPC: B01D35/00
Filed: 1984-05-14
Abstract: A continuous separation apparatus and method which continuously purges, washes, dries and removes solids from a slurry 10. A separator 15 comprises a casing 22, a horizontal rotary screen within the casing, a fixed scraper mounted in the casing above the screen, an inlet conduit 25 on one side of the scraper for depositing slurry on the screen to form a layer as the screen rotates, an outlet conduit 40 on the other side of the scraper and gas nozzles for directing a gas stream at the solids as they encounter the scraper, entraining them and directing them through the outlet conduit 40. The screen divides the interior of casing 22 into respective upper and lower chambers 23 and 24 that are sealed from one another except through the screen. In operation, the gas stream carries the entrained solids to a separate receiver 17. The gas is then recirculated at 45 and enters the upper chamber 23 of the separator at a slightly positive pressure. The lower chamber 24 is evacuated by evacuation means 20 so that a portion of the gas in the upper chamber passes through the slurry layer to displace liquid through the screen while further amounts of the gas cause additional drying of the solids so that they are of a suitably low liquid content when they encounter the fixed scraper and are entrained out of the separator. The recovered liquid is automatically degassified as it falls through the lower chamber 24 prior to its removal at 30. <IMAGE>
Patent GB-2162015-A (GB)
Title: Method of screen printing
Inventor: MAKIN WILLIAM JAMES
IPC: H04N1/52
Filed: 1984-05-23
Abstract: A method is described for producing a screen for printing a selected colour of a photographic image in which each colour area of the image comprises a plurality of component colour islands which together produce the colour perceived for said area. The method comprises scanning the image with electronic detector means to detect the colour islands of a selected scanned colour. A printing screen is then prepared from a blank of material by forming in the material a pattern of apertures which extend uninterrupted through the entire thickness of the material under the control of information obtained from the detector means. There is thus produced a printing screen with a pattern of apertures corresponding to the pattern of colour islands as of the scanned colour islands in the photographic image.
